What is the EMS system?

EMS stands for Energy Management System in the construction industry. An energy management system is a tool that  controls and reduces energy use in buildings. An EMS monitors, controls, and optimises the performance of the energy-consuming devices. For example, a BCA contractor can set up an EMS to automatically adjust the air conditioning. It can adjust the temperature depending on the number of people and weather.


What are examples of energy management systems?

Examples of energy management systems include:

Building Automation Systems (BAS). BAS controls the building's heating, ventilation, air conditioning (HVAC) and lighting. It is common in commercial buildings. For example, a BAS can adjust the temperature based on occupancy and the hot weather in Singapore.

Home Energy Management Systems (HEMS). These systems help homeowners manage their energy use efficiently. They control smart appliances and solar panels. Home energy management systems also monitor and provide energy usage data. It lets homeowners schedule when to turn off lights and can be connected to an app.


What are the 3 parts of energy management?

The three parts of energy management are:

Monitoring - Monitor your energy use. Identify patterns in energy usage and find areas for improvement. For example, you can use smart metres to track how electricity is used on a daily basis.

Control - Implement measures to regulate energy usage. You can control energies like turning off lights via an app or at automatic times when lights are not in use.

Optimisation - Improve energy efficiency by upgrading technology to use electricity optimally. For example, you can replace old HVAC systems with newer energy-efficient models.


What is the main goal of an energy management system?

The main goal of an energy management system is to reduce energy consumption and cost. It is difficult to optimise energy consumption while maintaining comfort and productivity. But technology and energy management systems allow us to achieve this.


How does an energy management system work?

An energy management system works by monitoring data, then making decisions based on that data. In a commercial building, it can help businesses to improve cost efficiencies. It can also help to reduce environmental impact. For example, an energy management system in a commercial building has sensors. After recording room temperature data, it can adjust air conditioning to save energy.


What is the difference between an energy management system and BMS?

An EMS focuses specifically on energy usage and efficiency. A Building Management System (BMS) manages all building systems. BMS management systems including heating, ventilation, air conditioning (HVAC), lighting, and security. While EMS is part of a BMS focused on energy, a BMS covers a broader range of functions.


What are the advantages and disadvantages of BMS?

Advantages of BMS includes:

  • Efficiency - BMS optimises building operations, reducing energy use and cost.
  • Comfort - Automatically adjusts conditions like temperature and lighting for comfort. This is important in commercial buildings where comfort affects workers' productivity.
  • Monitoring - Provides real-time data on building operations. It is important in helping the building management to keep conditions in check.

Disadvantages of BMS includes:

  • Cost - High initial investment for installation and setup. Hardwares for every room on every floor can be expensive. Software to get to decision making on the data can also be costly.
  • Complexity - Can be complex to manage, especially for those without technical expertise.
  • Dependency - Over-reliance on automated systems may lead to issues if the system fails.
